I wish to add that my PSA was at a fairly level 7 and my doctor was not too concerned about it but since my dads family had a history of it, grandfather died of it, 2 of my uncles died of it, one cousin died of it, and my father had prostate cancer (he died at 95 but not of cancer) I forced the doctor to get a biopsy which I had to argue like hell for.(my family doctor retired so I had a fairly new doctor) I had the biopsies( and man was that painful) but as it turned out of the 12 samples taken the average gleason was 9.5. This even though my psa was level at 7. I had a robotic radical surgery at at that time I developed instant ED This is over 6 years ago now and the nerves has only slowly grown but not to the stage of being able to have a normal errection
